Edited by Neil H Cogan, a well-versed legal scholar of constitutional law, civil rights, and civil and criminal procedures, this volume is a collection of papers on a central issue of governance in the United States -- the power of the states to object to and cancel federal laws with which they disagree. For eighty-one years, from the ratification of the Constitution to the end of the Civil War, the issue of state power was the central issue of governance. Chapters address the history and legal arguments for three assertions of such state power: interposition, nullification, and secession. Currently in several states, nullification measures are before the legislatures. During the recent Texas gubernatorial campaign, secession was discussed by two of the major candidates. The Tea Party Movement is reflective of a broader movement to limit federal intervention in state matters. The publication of this collection provides an intelligent voice to the national debate.
